Description

The course Gear and Gear Trains: Theory and Design Concepts is designed to provide  a comprehensive understanding of the principles, analysis, and design of gears and gear train systems. This course covers the fundamental concepts of gear geometry, classification, and tooth profiles, focusing on the Law of Gearing, which ensures smooth and uniform power transmission. Course helps to explore various types of gears, including spur, helical, bevel, and worm gears, and analyze their working principles, applications, and performance in mechanical systems. It helps in the understanding of the various terminologies that are important for gear design such as module, pitch circle, circular pitch, concept of length of the path of contact, length of the arc of contact etc. It also enables the understanding of tooth profiles  i.e. cycloid and involute profiles , their comparison and systems of gear teeth that generally used in sectors i.e automobile, aerospace and other manufacturing sectors.  Furthermore, course also focus on design and analysis of gear trains, such as simple, compound, reverted and epicyclic systems, used in diverse engineering applications. How to calculate the speed ratio or train value during power transmission from driver to driven gear. Importance of idle or intermediate gears during power transmission.
